​前言：

要说小时候称霸所有翻盖手机的小游戏，除了贪吃蛇，那就是推箱子了。

​​​控制小人将所有箱子放到指定位置，就是这样简简单单的操作，陪伴我度过了无数个没有动画片的时光。

​这个画面是不是特别熟悉？

小编也是从玩「推箱子」那个年代过来的人。那时，我拿个学习机，在老师眼皮子底下，通过了一关又一关。现在想起来，依然觉得很快乐。

今天一天都没给大家更新游戏了，看大家饥渴难耐的样子，也是时候要开始准备了。

那么今天为大家准备了童年经典游戏——推箱子，有看中就赶紧上车入手吧~

1.游戏规则

推箱子游戏是一款可玩性极高的策略解谜手游，游戏中玩家将扮演一名可爱Q萌的角色，

我们需通过将场景内的箱子，推送到合适的位置上进行摆放，才可以轻松获得游戏胜利。

整个过程虽然极其简单，但极需玩家动脑思考，充分的利用有效地空间，合理得将箱子推送到指定位置，从而获得游戏胜利。

不仅如此，游戏整体画风十分简洁清爽，采用了简单和程式化的图形设计，给予了玩家前所未有的体验感哦。

2.材料准备

玩家、箱子、背景等图片素材：

​3.环境安装

Python3.6、pycharm、pygame游戏模块不能少。

pip install pygame

**导入游戏的素材，**增加游戏元素

 def addElement(self, elem_type, col, row):
        if elem_type == \'wall\':
            self.walls.append(elementSprite(\'wall.png\', col, row, cfg))
        elif elem_type == \'box\':
            self.boxes.append(elementSprite(\'box.png\', col, row, cfg))
        elif elem_type == \'target\':
            self.targets.append(elementSprite(\'target.png\', col, row, cfg))

4.游戏开始、结束界面设置

def startInterface(screen, cfg):
    screen.fill(cfg.BACKGROUNDCOLOR)
    clock = pygame.time.Clock()
    while True:
        button_1 = Button(screen, (95, 150), \'开始游戏\', cfg)
        button_2 = Button(screen, (95, 305), \'退出游戏\', cfg)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()
            if event.type == pygame.MOUSEBUTTONDOWN:
                if button_1.collidepoint(pygame.mouse.get_pos()):
                    return
                elif button_2.collidepoint(pygame.mouse.get_pos()):
                    pygame.quit()
                    sys.exit(0)
        clock.tick(60)
        pygame.display.update()
 
def endInterface(screen, cfg):
    screen.fill(cfg.BACKGROUNDCOLOR)
    clock = pygame.time.Clock()
    font_path = os.path.join(cfg.FONTDIR, \'simkai.ttf\')
    text = \'机智如你~恭喜通关!\'
    font = pygame.font.Font(font_path, 30)
    text_render = font.render(text, 1, (255, 255, 255))
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()
        screen.blit(text_render, (120, 200))
        clock.tick(60)
        pygame.display.update()

如下：

​

**​****设置游戏的界面​，**导入关卡地图。

class gameInterface():
    def __init__(self, screen):
        self.screen = screen
        self.levels_path = cfg.LEVELDIR
        self.initGame()
    def loadLevel(self, game_level):
        with open(os.path.join(self.levels_path, game_level), \'r\') as f:
            lines = f.readlines()
        # 游戏地图
        self.game_map = gameMap(max([len(line) for line in lines]) - 1, len(lines))
        # 游戏surface
        height = cfg.BLOCKSIZE * self.game_map.num_rows
        width = cfg.BLOCKSIZE * self.game_map.num_cols
        self.game_surface = pygame.Surface((width, height))
        self.game_surface.fill(cfg.BACKGROUNDCOLOR)
        self.game_surface_blank = self.game_surface.copy()
        for row, elems in enumerate(lines):
            for col, elem in enumerate(elems):
                if elem == \'p\':
                    self.player = pusherSprite(col, row, cfg)
                elif elem == \'*\':
                    self.game_map.addElement(\'wall\', col, row)
                elif elem == \'#\':
                    self.game_map.addElement(\'box\', col, row)
                elif elem == \'o\':
                    self.game_map.addElement(\'target\', col, row)

因为游戏界面面积>游戏窗口界面, 所以需要根据人物位置滚动。

 def scroll(self):
        x, y = self.player.rect.center
        width = self.game_surface.get_rect().w
        height = self.game_surface.get_rect().h
        if (x + cfg.SCREENSIZE[0] // 2) > cfg.SCREENSIZE[0]:
            if -1 * self.scroll_x + cfg.SCREENSIZE[0] < width:
                self.scroll_x -= 2
        elif (x + cfg.SCREENSIZE[0] // 2) > 0:
            if self.scroll_x < 0:
                self.scroll_x += 2
        if (y + cfg.SCREENSIZE[1] // 2) > cfg.SCREENSIZE[1]:
            if -1 * self.scroll_y + cfg.SCREENSIZE[1] < height:
                self.scroll_y -= 2
        elif (y + 250) > 0:
            if self.scroll_y < 0:
                self.scroll_y += 2

设置玩家的精灵类，可上下左右移动等。

class pusherSprite(pygame.sprite.Sprite):
    def __init__(self, col, row, cfg):
        pygame.sprite.Sprite.__init__(self)
        self.image_path = os.path.join(cfg.IMAGESDIR, \'player.png\')
        self.image = pygame.image.load(self.image_path).convert()
        color = self.image.get_at((0, 0))
        self.image.set_colorkey(color, pygame.RLEACCEL)
        self.rect = self.image.get_rect()
        self.col = col
        self.row = row
    \'\'\'移动\'\'\'
    def move(self, direction, is_test=False):
        # 测试模式代表模拟移动
        if is_test:
            if direction == \'up\':
                return self.col, self.row - 1
            elif direction == \'down\':
                return self.col, self.row + 1
            elif direction == \'left\':
                return self.col - 1, self.row
            elif direction == \'right\':
                return self.col + 1, self.row
        else:
            if direction == \'up\':
                self.row -= 1
            elif direction == \'down\':
                self.row += 1
            elif direction == \'left\':
                self.col -= 1
            elif direction == \'right\':
                self.col += 1
    \'\'\'将人物画到游戏界面上\'\'\'
    def draw(self, screen):
        self.rect.x = self.rect.width * self.col
        self.rect.y = self.rect.height * self.row
        screen.blit(self.image, self.rect)
 
 
\'\'\'游戏元素精灵类\'\'\'
class elementSprite(pygame.sprite.Sprite):

        self.image_path = os.path.join(cfg.IMAGESDIR, sprite_name)
        self.image = pygame.image.load(self.image_path).convert()
        color = self.image.get_at((0, 0))
        self.image.set_colorkey(color, pygame.RLEACCEL)
        self.rect = self.image.get_rect()
        # 元素精灵类型
        self.sprite_type = sprite_name.split(\'.\')[0]
        # 元素精灵的位置
        self.col = col
        self.row = row
    \'\'\'将游戏元素画到游戏界面上\'\'\'
    def draw(self, screen):

游戏关卡循环，当某个关卡过不去的时候，想重新来按住R键即可返回本关卡。

def runGame(screen, game_level):

    game_interface.loadLevel(game_level)

    text = \'按R键重新开始本关\'
    font = pygame.font.Font(font_path, 15)
    text_render = font.render(text, 1, (255, 255, 255))
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit(0)
            elif event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:

                    break
                if event.key == pygame.K_r:
                    game_interface.initGame()
                    game_interface.loadLevel(game_level)
        game_interface.draw(game_interface.player, game_interface.game_map)
        if game_interface.game_map.levelCompleted():
            return
        screen.blit(text_render, (5, 5))
        pygame.display.flip()
        clock.tick(100)

如下：

​

​判断****该关卡中所有的箱子是否都在指定位置, 在的话就是通关了。

 def levelCompleted(self):
        for box in self.boxes:
            is_match = False
            for target in self.targets:
                if box.col == target.col and box.row == target.row:
                    is_match = True
                    break
            if not is_match:
                return False
        return True

效果图第二关卡如下：
